Installing the Alignak backend is an easy operation.
The different installation methods are detailed in the documentation but the most easy way is to:

# On Debian base distro# Assuming that you already have a running MongoDB instancesudoaptinstalluwsgiuwsgi-plugin-pythonalignak-backend

Once installed, the backend is ready to run and you can start with:

sudosystemctlenablealignak-backendsudosystemctlstartalignak-backend

Configuring the Alignak backend is made easy thanks to a settings.json file.
The default configuration makes the backend run on the local interface, on port 5000, and it creates an admin user that can be used to log-in.

Once installed, the backend needs to be related to Alignak daemons. This is achieved thanks to the Alignak backend modules.
